Through DTU products, devices can transmit data wirelessly. No matter how far apart they are, they can interact and process data through a wireless network.

What is the DTU in the Internet of Things? The Chinese name of DTU is "wireless data transmission terminal". According to the different transmission methods and networks used in data transmission, DTU devices can be divided into many types, such as: 4G DTU, NB-IOT DTU , LORA DTU, GPRS DTU.

Industrial computers generally use assembly lines and internal installation of independent equipment, which is inconvenient for wired broadband access and wifi networking. Therefore, 4G communication module industrial-grade plug-in IoT sim card wireless routing is the main method for industrial computer networking.

Compared with ordinary routers, 4G industrial routers can connect more network devices. 4G industrial routers can connect at least two or more network devices, and can connect hundreds of IPs to the Internet at the same time. Such efficient operation must be equipped with powerful The blessing of forwarding performance and the number of tape drives can be realized;

Under normal circumstances, factory production will use this "monster" to solve a variety of complex problems, thereby simplifying the problem and greatly improving the efficiency of the factory.And ordinary home routers can only meet a certain range, low efficiency, low strength, low density, forwarding performance and limited tape drive capacity.

Whether it is 4G industrial routers or routers of other networks, their working principles are roughly the same;It's just that more 4G industrial routers will be used in the industry. Because 4G industrial routers are adaptable to resist harsh external environments, the software and hardware coordination capabilities of 4G industrial routers will be stronger.

How to select the 4G industrial routers with the strongest performance and the best brand quality in the vast ocean of routers has become a key consideration for customers. Up to the problem.Routers that are widely used in life, as long as they can ensure safe Internet access, the price generally ranges from a few hundred RMB to a few thousand RMB;

When a 4G industrial router is put into actual use, it needs to have three major parts: a power adapter, a WiFi antenna, and a SIM card to use in combination.Under normal circumstances, after the user purchases a 4G industrial router, the manufacturer will send it along with the 4G industrial router with a power supply and antenna, without additional purchase;

Since the two IoT technologies of NB-IoT and LoRa are both low power consumption, the current consumption (peak current and average current) of the node can be more detailed.The synchronization protocol of the cellular network must also be used, and the terminal must be regularly connected to the Internet and have a short downlink delay.LoRaWAN uses the asynchronous ALOHA protocol, which needs to ···

Wireless industrial routers can be widely used in fast networking of self-service terminals (advertising machines, self-service vending machines, self-service express mail boxes), smart water services (discharge flow monitoring of hydropower stations, unattended pumping stations, urban waterlogging monitoring and early warning), intelligent industrial control (mechanical equipment networking) , In···
